The AC50 (defined in the America's Cup rules as AC class yacht) is a wing sail catamaran box rule, governing the construction and operation of the yachts to be used in the 35th America's Cup (for inshore racing in the 2017 Louis Vuitton Cup selection series and the 2017 America's Cup).
The class replaced the AC72 class used in the prior 2013 edition (34th America's Cup). The class does not prohibit the use of hydrofoils so L-shaped daggerboard elevators as well as T-shaped rudder elevators, which were previously used in AC72s, are expected in the competition. Prototype versions of AC50 class crossbeams, wings, appendage, steering and trimming systems have been tested by all syndicates on AC45 platforms as surrogate yachts. The class features hydraulic control of the solid wing. Motors and computers are banned in the class. Each challenger team is only allowed to build one AC50 for competition.
